Sažetak

We present a simple theoretical analysis of the Burstein-Moss shift in ultrathin films of bismuth in presence of crossed electric and quantizing magnetic fields in the presence of spin and broadening of Landau levels. The numerical results are presented for McClure and Choi, hybrid, Cohen, Lax and ellipsoidal parabolic energy band models. It was found that the shift increases for thinner films and in weaker magnetic field. In addition, the shift increases with increasing electron concentration, and the quantum oscillations, in accordance with the Mc Clure and Choi model, show up much more significantly than with other models of bismuth.
